I cant say, unless you specify your requirements.

The problem is the undefined latency on the host CPU (LINUX). You can 
workaround that by using the libpruio trigger options. In MM you can start 
the measurement by up to four trigger events. Connect your external clock 
and let the PRU watch a GPIO pin or an analog input and start the 
measurement on a certain state. Check out the triggers

example.
